Abstract: Critical care medicine in China has developed rapidly and played an irreplaceable role in the treatment of critically ill patients, emergency disasters and public health events. The standardized training of specialists is not only an important part of medical education after graduation, but also a conventional way to train qualified specialized clinicians. As the second batch of national pilot specialties, critical care medicine has established a national unified specialist training system, which has become an important way to cultivate professionals. This study compares the similarities and differences of critical care medicine specialty training in foreign countries from the aspects of training system and platform construction, so as to provide reference for promoting the continuous improvement of critical care specialist training system in China.
